1200mm / 47 inches is very short for such large wicks. The flames will be very close to the handle and your hands. I'll build it you want it but you have been warned.

1400mm / 55 inches (500g) this is the most popular length for this wick size.

1500mm / 59 inches (525g) OR 1600mm / 63 inches or any other length you prefer up to 1.9 metres.

When this staff is moved slowly the three flames join up and create a HUGE 250mm/10 INCH FLAME with the weight and fuel use of just 150mm/6 inches of wick - WIN! When moved faster the flames become smaller and you see them all as 6 separate flame trails. A super fun staff as well as an impressive prop for fire shows. If you spin so fast that the flames become very small, you may want to consider getting one made with larger wicks/flames like 65mm (2.5 inch) wide or even 100mm (4 inch) wide.
